OP thank you for this crystal clear guide. The day before I see your thread I was reverse engineering a site, but with the help of many different tools. Check this, write it down, check that, write it down, then scratching my head, then start to look from different angle with other tool and and repeat the steps above. On the next they, I woke up (just before to start doing the same thing as last night), login into the forum and saw your post. But I got one question:
How accurate do you think some of this site metrics are, I mean to what extent you can trust them?
